I-Kubernetes uhlelo lomthombo ovulekile lokusebenzisa ngokuzenzakalela ukuthunyelwa, ukukala, kanye nokuphathwa kwezinhlelo zokusebenza eziqukathiwe.
Yakhiwe ekuqaleni yiGoogle, ukuthuthuka kwayo kwanikezwa i-database yomthombo ovulekile we-Cloud Native Computing Foundation (CNCF), enike amandla ubuchwepheshe besitsha ukuthi bukhule ngokushesha ekuvuthweni, ngenxa yeminikelo yezikhulu zobuchwepheshe (njenge-AWS, i-Oracle, IBM, iMicrosoft, i-Alibaba, ne-VMware) nezinye izinkampani ezinkulu.
IKubernetes inezinto ezimbili ezibalulekile:
- iqoqo lama-master node asebenza njengendiza yokulawula
- iqoqo lama-node asebenza njengama-workhorses asebenza umthwalo owenziwe ngeziqukathi
Lapho kuthunyelwa umthwalo wamakhonteyina amaningi kumaKubernetes, uhlelo lokulawula lukhetha indawo eyodwa noma eziningi zabasebenzi ukusingatha iziqukathi.
Izolo, iqembu elibhekele ukuthuthukiswa kwalo lenze isimemezelo sokutholakala kweKubernetes 1.14 okubandakanya ukuthuthuka okungama-31.
Yikuphi okuvelele kule nguqulo kuyashesha nokwesekwa kwemithwalo yemisebenzi eminingi eKubernetes, ngezici ezintathu eziyinhloko eziya ekutholakaleni okujwayelekile nokusebenza okuphawulekayo kokuphepha okuthuthela ku-beta.
Sekukonke, inguqulo ifaka ukuthuthuka okungama-31: eziyi-10 manje esezinguqulweni ezizinzile, eziyi-12 ku-beta, nezintsha eziyisikhombisa ezintsha.
Yini okusha in Kubernetes 1.14
KuKubernetes 1.14 imibhalo ye-kubectl ibhalwe kabusha kugxilwe ekuphathweni kwezinsizakusebenza kusetshenziswa ukumiswa kwesisetshenziswa esichazayo.
Itholakala njengencwadi enesixhumanisi semibhalo emikhulu ye-Kubernetes. Kukhona nelogo ye-kubectl nemaskandi ebizwa nge-kubee-cuddle.
Okunye okuphawulekayo kumemezelo weKubernetes 1.14 wokuthi amandla wokudalula amasethingi wokucushwa kwethuluzi lokucushwa le-YAML ama-kustomize ayatholakala ku-bectl kusetshenziswa ifulegi le -k ukuthola imiyalo yokusebenzisa.
Ukwenza ngokwezifiso kusiza abasebenzisi ukubhala nokusebenzisa kabusha i-Resource Config kusetshenziswa imiqondo yendabuko yeKubernetes. Imibhalo yalezi zici ezintsha iyatholakala.
Indlela ye-kubectl isiyatholakala ngohlobo oluzinzile. Ivumela onjiniyela ukuthi bashicilele imiyalo yabo yangokwezifiso ye-bectl njengama-binaries ahlukile.
Amavolumu asendaweni aqhubekayo manje asenguqulweni ezinzile. Benza isitoreji esinamathiselwe endaweni sitholakale njengomthombo wevolumu ophikelelayo.
Ama-ID enqubo (ama-PID) ashintshela ku-beta. Lesi sixazululo sivumela abaphathi ukuthi banikeze i-pod PID ekuhlukanisweni kwe-pod ngokuzenzakalela ukusetha inani lama-PID nge-pod ngayinye. Isici esengeziwe se-alpha yikhono lokugcina ama-PID amaningi anikezwe ama-User Pods.
Izithuthukisi zokusekela kumaKubernetes 1.14
Ngalokhu kukhishwa okusha kweKubernetes 1.14 Kungezwe ukusekelwa kweWindows Server 2019 kwama-node neziqukathi zabasebenzi.
Mayelana nalokhu U-Aaron Crickenberger, onguNjiniyela Omkhulu Wokuhlola kwaGoogle ubeke amazwana kanjena:
Ukufaka iWindows njengomthwalo ongaba khona womsebenzi kusho ukuthi bekufanele sichaze ngokunembile okwenziwa yiKubernetes futhi okungasekeli kwezinye izindawo.
Ngicabanga ukuthi izici ezinjengamasango wokulungela i-pod kanye nokubekwa phambili kwe-pod nokukhethwa kuzosiza kakhulu ekuvumela abantu ukuthi bahlele imithwalo yemisebenzi esezingeni eliphakeme. Ezinye izinhlelo zingadinga izindlela eziqonde ngqo zokukhombisa ukuthi bakulungele yini ukuphatha ithrafikhi futhi le misebenzi inikeza lezi zindlela kubo.
Ngakolunye uhlangothi singathola ukuthi iKubernetes 1.14 iza nokuxhaswa kwamanethiwekhi angaphandle kwesihlahla ane-Azure-CNI, i-OVN-Kubernetes neFlannel, Umsebenzi uyaqhubeka nokufaka iCalico nabanye abahlinzeki benethiwekhi abathandwayo
Ukusekelwa kuphinde kwathuthukiswa kuma-pods, izinhlobo zensizakalo, abalawuli bomthwalo wokusebenza, kanye namamethrikhi / quotas ukwamukela kangcono ukusebenza okuhlinzekwa yiziqukathi zeLinux.
Ukubekwa phambili kwePod kuvumela isihleli seKubernetes ukuhlela umsebenzi ngokubaluleka nokususa ama-pods amancane uma kunesidingo.
Isingeniso sePod Readiness Gates singenisa iphuzu lokwelulwa kwempendulo yangaphandle ngokulungela i-pod.
Lokhu kukhishwa kunikeza ukuqina okuzenzakalelayo kwezibopho zeqhaza lokutholwa kweqoqo le-RBAC.
Uma ufuna ukwazi okuthe xaxa ngalokhu kukhishwa okusha, kanye nokulanda nokusebenzisa le nguqulo entsha. Ungavakashela isixhumanisi esilandelayo.
